Application Scenarios & Design Considerations

3.3V software-selectable multiprotocol transceiver.

Alternative Part Number

  • MAX3160EAP+ --: Multiprotocol transceiver supporting RS-232/RS-485/RS-422, functionally comparable to the LTC2845 software-selectable multiprotocol transceiver; different series and pin-compatible class.
  • SP334CT-L --: Multiprotocol serial transceiver with selectable RS-232/RS-485/RS-422 modes, a common cross for LTC284x multiprotocol parts from a different vendor series.
  • ADM3311EARSZ --: Multichannel serial transceiver offering similar multiprotocol interface functionality; different naming and series, suitable as a design alternative with layout review.
  • SP339EER1-L --: Multiprotocol serial transceiver supporting RS-232/RS-485, functionally comparable to the LTC2845 and suitable for similar applications.
  • ADM3307EARUZ --: Multichannel RS-232/RS-485 transceiver with comparable feature set, offering a viable alternative when the original part is unavailable.
